Prime Minister Malcolm Turnbull has placed a number of frustrated phone calls to Liberal MPs who are threatening to cross the floor on same sex marriage.
Mr Turnbull phoned Queensland MP Trevor Evans and WA MP Dean Smith over reports they were planning to introduce a private member's bill and cross the floor, according to The Daily Telegraph.
It is understood he asked them to abide by the Liberal Party policy, which is to make a decision on the issue through a national plebiscite.
If the private member's bill is successful, it is predicted it will spell the end of Mr Turnbull's reign and possibly the end of the Coalition agreement.
Prime Minister Malcolm Turnbull faces a leadership spill if he does not stop moderate MPs from crossing the floor. He has reportedly called some of the MP's involved in a rebel plan to legalise same sex marriage to encourage them to stick to the Coalition's policy of a plebiscite
The agreement in question has never been publicly available, but is understood to contain an agreement that the legalisation of same sex marriage can only come about through a plebiscite.
